The D2d (Vitamin D and type 2 diabetes) study has investigated whether daily supplementation with vitamin D3 can reduce the risk for progression to type 2 diabetes in people with prediabetes based on at least two criteria.
Participants were enrolled regardless of vitamin D status and randomly assigned to take vitamin D3 at a dose of 4000 IU – higher than the recommended 600–800 IU/day supplemental dose – or matching placebo. The aim was to continue treatment for an average of 3 years.
